Force the DRA7xx Ethernet internal clock source to stay enabled
per TI erratum i877:
http://www.ti.com/lit/er/sprz429h/sprz429h.pdf
Otherwise, if the Ethernet internal clock source is disabled, the
chip will age prematurely, and the RGMII I/O timing will soon
fail to meet the delay time and skew specifications for 1000Mbps
Ethernet.
This fix should go in as soon as possible.

Merge tag 'for-v4.6/omap-hwmod-b' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v4.6/soc
ARM: OMAP2+: second set of hwmod changes for v4.6
These patches add RTC support for the AM43xx, and add support for
the DRA7xx eDMA controller's TPCC, TPTC0, and TPTC1 IP blocks.
Also included is a workaround for PRCM hardreset control of the DRA7xx
PCIe subsystem.
Note that I do not have a DRA7xx board, and therefore cannot
test any patches for that SoC family.
Basic build, boot, and PM test logs can be found here:
http://www.pwsan.com/omap/testlogs/omap-hwmod-b-for-v4.6/20160301021258/
Add hwmod data for the eDMA blocks:
- TPCC: Third-party channel controller
- TPTC0: Third-party transfer controller 0
- TPTC1: Third-party transfer controller 1
The TPCC's clock gating status follows the status of its clock and
power domain. This means that the hwmod code can not directly control
the TPCC enable/disable status.

Add a custom reset handler for DRA7x PCIeSS. This
handler is required to deassert PCIe hardreset lines
after they have been asserted.
This enables the PCIe driver to access registers after
PCIeSS has been runtime enabled without having to
deassert hardreset lines itself.
With this patch applied, used lspci to make sure
connected PCIe device enumerates on DRA74x and DRA72x
EVMs.

We still have some boards booting in legacy mode and they will need to have
the device/slave -> filter_fn mapping so we can convert the OMAP drivers
to use the new dmaengine API for requesting channels.
Only some OMAP24xx and OMAP3xxx boards can boot in legacy mode which means
we only need to provide the map for these SoCs.

If syscon_config.max_register is initialized like it should be, we have
omap_ctrl_read/write() fail with out of range register access at least
for omap3.
We have omap3.dtsi setting up a regmap range for scm_conf, but we now
have omap_ctrl_read/write() also attempt to use the regmap. However,
omap_ctrl_read/write() is also used for other register ranges in the
system control module (SCM).
Let's fix the issue by just removing the regmap_read/write() usage for
control module as suggested by Tero Kristo <t-kristo@ti.com>.

If a driver PM runtime is disabled via sysfs, and the module is
unloaded, PM runtime can't do anything to disable the device. Let's
let the interconnect disable the device on BUS_NOTIFY_UNBOUND_DRIVER.
Otherwise omap_device will produce and error on the following module
reload. This can be easily tested with something like:
# modprobe omap_hsmmc
# echo on > /sys/devices/platform/68000000.ocp/4809c000.mmc/power/control
# rmmod omap_hsmmc

Drivers using pm_runtime_use_autosuspend() may not get disabled after
-EPROBE_DEFER. On the following device driver probe, hardware state
is different from the PM runtime state causing omap_device to produce
the following error:
omap_device_enable() called from invalid state 1
And with omap_device and omap hardware being picky for PM, this will
block any deeper idle states in hardware.
Let's add a proper error message so driver writers can easily fix
their drivers for PM.
In general, the solution is to fix the drivers to follow the PM
runtime documentation:
1. For sections of code that needs the device disabled, use
pm_runtime_put_sync_suspend() if pm_runtime_set_autosuspend() has
been set.
2. For driver exit code, use pm_runtime_dont_use_autosuspend() before
pm_runtime_put_sync() if pm_runtime_use_autosuspend() has been
set.
Let's not return with 0 from _od_runtime_resume() as that will
eventually lead into new drivers with broken PM runtime that will
block deeper idle states on omaps.

There's a huge number of changes here, and it's challenging to give a crisp
overview of just what is in here. To start with:
New boards:
- TI-based DM3730 from LogicPD (Torpedo)
- Cosmic+ M4 (nommu) initial support (Freescale Vybrid)
- Raspberry Pi 2 DT files
- Watchdog on Meson8b
- Veyron-mickey (ASUS Chromebit) DTS
- Rockchip rk3228 SoC and eval board
- Sigma Designs Tango4
Improvements:
- Improved support for Qualcomm APQ8084, including Sony Xperia Z DT files
- Misc new devices for Rockchip rk3036 and rk3288
- Allwinner updates for misc SoCs and systems
... and a _large_ number of other changes across the field. Devices
added to SoC DTSI and board DTS files for a number of SoC vendors, new
product boards on already-supported SoCs, cleanups and refactorings of
existing DTS/DTSI files and a bunch of other changes.

Pull ARM DT updates from Olof Johansson:
"As usual, the bulk of this release is again DT file contents.
There's a huge number of changes here, and it's challenging to give a
crisp overview of just what is in here. To start with:
New boards:
- TI-based DM3730 from LogicPD (Torpedo)
- Cosmic+ M4 (nommu) initial support (Freescale Vybrid)
- Raspberry Pi 2 DT files
- Watchdog on Meson8b
- Veyron-mickey (ASUS Chromebit) DTS
- Rockchip rk3228 SoC and eval board
- Sigma Designs Tango4
Improvements:
- Improved support for Qualcomm APQ8084, including Sony Xperia Z DT files
- Misc new devices for Rockchip rk3036 and rk3288
- Allwinner updates for misc SoCs and systems
... and a _large_ number of other changes across the field. Devices
added to SoC DTSI and board DTS files for a number of SoC vendors, new
product boards on already-supported SoCs, cleanups and refactorings of
existing DTS/DTSI files and a bunch of other changes"

Adds a function that sets the pointer to dev_pm_domain in struct device
and that warns if the device has already finished probing. The reason
why we want to enforce that is because in the general case that can
cause problems and also that we can simplify code quite a bit if we can
always assume that.
This patch also changes all current code that directly sets the
dev.pm_domain pointer.

Commit 63aa945b10 ("memory: omap-gpmc: Add Kconfig option for debug")
unified the GPMC debug for the SoCs with GPMC. The commit also left out
the option for HWMOD_INIT_NO_RESET as we now require proper timings for
GPMC to be able to remap GPMC devices out of address 0.
Unfortunately on Nokia N900, onenand now only partially works with the
device tree provided timings. It works enough to get detected but the
clock rate supported by the onenand chip gets misdetected. This in turn
causes the GPMC timings to be miscalculated and this leads into file
system corruption on N900.
Looks like onenand needs CS_CONFIG1 bit 27 WRITETYPE set for for sync
write. This is needed also for async timings when we write to onenand
with omap2_onenand_set_async_mode(). Without sync write bit set, the
async read for the onenand ONENAND_REG_VERSION_ID will return 0xfff.
Let's exit with an error if onenand rate is not detected. And let's
remove the extra call to omap2_onenand_set_async_mode() as we only need
to do this once at the end of omap2_onenand_setup_async().
